The fire alarm system shall detect the initial signs of fire at an early stage of its occurrence and shall not give false positives. It also depends on balancing the fire alarm loop with the fire receiving control device. The use of devices from different manufacturers in the construction of a fire alarm may result in the malfunctioning of such a system and giving false signals.The article presents the results of the analysis of the state of non-address fire control receivers of different manufacturers, depending on the mode of the fire alarm loop, in which he may be. The received generalized nomogram of states of non-address control devices depending on the resistance of the fire plume is presented. A method for determining the resistance of loop elements against different fire detectors is proposed and an appropriate algorithm is developed.
